Detailed Description

In general, automobiles can be placed on a single-layer carriage frame or a foldable double-layer carriage frame. Taking a single-layer carriage as an example, referring to fig. 3-6, a track adjusting mechanism of a carriage is disclosed. The carriage frame comprises two groups of symmetrical lanes 1 which are longitudinally arranged, the front end part of the lane 1 is provided with a wheel tread adjusting mechanism, and in other embodiments, the wheel tread adjusting mechanism can also be arranged at the rear end part of the lane 1, namely, the utility model does not limit the longitudinal front and rear positions of the wheel tread adjusting mechanism on the lane. The track adjusting mechanism comprises two adjusting mechanisms 2 which are longitudinally arranged in sequence, wherein at least one adjusting mechanism 2 can longitudinally adjust the position. In this embodiment, the two adjusting mechanisms 2 can adjust their longitudinal positions, and they are matched together for use. The two sides of the lane 1 are longitudinally and uniformly provided with a plurality of first through holes 13, the two sides of the adjusting mechanism 2 are provided with second through holes 24, and the second through holes 24 and different first through holes 13 can be fixed through the connecting shaft 4, so that the adjusting mechanism 2 can be fixed at different longitudinal positions on the lane 1, namely, the positions of the adjusting mechanism 2 can be longitudinally adjusted when the second through holes 24 and the longitudinally arranged different first through holes 13 are fixed. In this embodiment, a plurality of second through holes 24 uniformly distributed longitudinally are used to fix the corresponding first through holes 13, so as to increase the stability of the adjusting mechanism 2.

The above provides a way to change the longitudinal position of the adjustment mechanism 2 on the lane 1, while a funnel-shaped groove 3 is provided between two longitudinally movable adjustment mechanisms 2, the groove 3 being intended for placing a tyre of a vehicle. When the vehicle is driven into the transportation frame for placement, the tires can sink into the funnel-shaped grooves 3, and the grooves 3 play a role in positioning and buffering of the vehicle. In this embodiment, the direction in which the vehicle is driven into the carriage is not limited, i.e. both the front and rear wheels of the vehicle have the opportunity to fall into the recess 3. The relative distance between the two adjusting mechanisms 2, namely the size of the groove 3, can be adjusted by changing the longitudinal position of the adjusting mechanisms 2, and the longitudinal position of the groove 3 on the lane 1, namely the position of different vehicles in the transporting frame can be adjusted, so that the groove 3 is adapted to tires of different vehicle types and different sizes, the transporting frame can adjust the wheel distance according to the vehicle types, and the transporting frame can be better adapted to the length of the vehicles and the size of the wheel distance.

To achieve the above functions, the specific structure of the lane 1 and the adjusting mechanism 2 is as follows:

The lane 1 includes a lane plate 11 and side members 12 longitudinally provided on both sides of the lane plate 11, and for convenience, the length of the lane plate 11 is shorter than the length of the side members 12, as shown in fig. 4. A plurality of first through holes 13 are uniformly arranged longitudinally on the side beam 12, and first forming holes 14 are uniformly distributed longitudinally on the lane plate 11. The side members 12 of the carriage frame are generally hollow, and the inside of the first through hole 13 needs to be reinforced by a welding sleeve, so that the first through hole 13 and the second through hole 24 are more firmly matched.

Referring to fig. 3, the track adjusting mechanism is disposed at one end of the lane board 11, that is, the two adjusting mechanisms 2 are sequentially disposed at the end of the lane board 11 longitudinally, and both sides of the adjusting mechanisms 2 are detachably connected with the side beams 12. Referring to fig. 5, the adjustment mechanism 2 includes an adjustment lane plate 21 and mounting beams 22 longitudinally disposed on both sides of the adjustment lane plate 21, the mounting beams 22 matching the contour of the side beams 12 and covering the side beams 12; the mounting beam 22 is provided with a second through hole 24, and when the second through hole 24 is not fixed with the first through hole 13, the mounting beam 22 can slide along the side beam 12 to drive the whole adjusting mechanism 2 to change the longitudinal position thereof. The plurality of second forming holes 25 are longitudinally and uniformly distributed on the adjustment lane plate 21, and the support beam 23 is transversely arranged at the bottom, so that the strength of the adjustment mechanism 2 can be increased.

Referring to fig. 6, the connecting shaft 4 has a head portion having a diameter larger than that of the second through hole 24 and a tail portion having a circular hole through which the opening tip passes. The tail of the connecting shaft 4 passes through the second through hole 24 and the first through hole 13 in sequence, and then the adjusting mechanism 2 and the side beam 12 are fixed relatively. While the head of the connecting shaft 4 is defined by the surface of the second through hole 24 and the tail is defined by the surface of the first through hole 13 by the cotter pin 5. Thus, by the cooperation of the first through hole 13 and the second through hole 24, the longitudinal positions of the two adjustment mechanisms 2 on the lane 1 can be adjusted.

Based on the above structure, the setting positions of the two adjusting mechanisms 2 are different, so that the two adjusting mechanisms 2 need to be distinguished, so that the following description is facilitated, referring to fig. 5: adjacent to the lane plate 11 is a second adjustment mechanism 2b and remote from the lane plate 11 is a first adjustment mechanism 2a. The first adjusting mechanism 2a is provided with a first inclined plane 2a1 on one side relative to the second adjusting mechanism 2b, the second adjusting mechanism 2b is provided with a second inclined plane 2b1 on one side relative to the first adjusting mechanism 2a, namely, the opposite sides of the lane adjusting plates 21 of the two adjusting mechanisms 2 are respectively provided with a first inclined plane 2a1 and a second inclined plane 2b1, and the first inclined plane 2a1, the second inclined plane 2b1 and the gap between the first inclined plane 2a1 and the second inclined plane 2b1 are mutually matched to form a groove 3. In order to place tires, the first inclined plane 2a1 and the second inclined plane 2b1 are required to be in an acute angle, and a funnel-shaped groove 3 is formed by matching with a horizontal gap between the first inclined plane 2a and the second inclined plane 2b, so that the tire sizes of different vehicles can be adapted by adjusting the positions between the first adjusting mechanism 2a and the second adjusting mechanism 2b, and the positioning buffer degree of the vehicles when driving into the placement can be adjusted.

Since the second adjustment mechanism 2b is close to the lane plate 11, the level of the adjustment lane plate 21 of the second adjustment mechanism 2b needs to be just higher than the lane plate 11, i.e. the bottom surface of the adjustment lane plate 21 of the second adjustment mechanism 2b is just higher than the top surface of the lane plate 11, so that the adjustment lane plate 21 can be covered on the lane plate 11 when the longitudinal position of the second adjustment mechanism 2b is changed.

The first forming holes 14 and the second forming holes 25 not only increase the friction of the tires on the lane 1 when the vehicle is driven into the carriage frame, but also provide fixing points for binding the tires, and the longitudinal spacing of the first forming holes 14 on the lane plate 11 is the same as the longitudinal spacing of the second forming holes 25 on the lane plate 21. Taking the longitudinal pitch as a base value, a value obtained by multiplying the base value by a natural number is taken as the pitch of the first through holes 13, and the pitch of the first through holes 13 in this embodiment is taken as a base value x 2. In the first adjusting mechanism 2a, each mounting beam 22 is provided with three second through holes 24, and the interval between the two through holes is a basic value of 2; when the first adjusting mechanism 2a is fixed to the side member 12, the side member 12 can be firmly connected to the side member by only two second through holes 24. In the second adjustment mechanism 2b, each mounting beam 22 is provided with five second through holes 24, and the distance between the two second through holes is 1, so that compared with the first adjustment mechanism 2a, the adjustment range of the second adjustment mechanism 2b is smaller and finer; when the second through hole 24 is fixed to the different first through hole 13, if the adjustment lane plate 21 and the lane plate 11 of the second adjustment mechanism 2b have a overlapping portion, referring to fig. 6, the second forming hole 25 and the first forming hole 14 of the overlapping portion can be completely overlapped, and the locking during the tire binding is not affected.

In summary, the wheel track adjusting mechanism of the utility model has the advantages that the wheel track adjusting mechanism can adjust the position of the vehicle in the vehicle frame when the vehicle is driven into place, and the vehicle frame can better adapt to the length and the size of the wheel track of the vehicle when the vehicle is in use as a whole; the two adjustment mechanisms 2 are mutually adjustable to fit the tire sizes of different vehicles, as seen from the stand alone use of the wheel tread adjustment mechanism. The foldable double-layer integral type carriage comprises an upper layer of foldable carriage platform and a lower layer of foldable carriage platform, each layer of carriage platform can correspond to the single-layer carriage frame, and the use situation of the wheel track adjusting mechanism is consistent. Whether the vehicle frame is a single-layer vehicle frame or a foldable double-layer vehicle frame, the track position on the vehicle frame platform can be adjusted according to the size of the vehicle, and the vehicle frame can be better adapted to different vehicle types in application.
